Remove 25 cards from the pack and allow the spectator to shuffle and cut the cards as much as they want then lay the 25 cards out in 5 rows of 5 cards face upwards from left to right in neat rows following a sort of grid pattern.
Ask the spectator to think of any one of the cards in any row and to tell you which row their card is located in. When they tell you, note the card* at the left hand end of the row. Take up the cards, beginning first at the last or right hand card of the
ottom line, placing it on the face of the card immediately above it and then place these 2 cards on top of the card immediately above, and so on up to the top.
Do this with each of the rows in turn and you should be left with 5 piles of cards on what was the top row.
Collect up the cards, placing the 5th (right hand) pile on top of the 4th, then this stack on top of the 3rd, then on top of the 2nd, etc, until you're left with a single stack of cards.
Then once again, keeping the cards face up, deal then into another 5 horizontal rows as before. Ask the spectator to tell you once again which row their card is located in. When they tell you, look along the top or the bottom row for the card which you noted* earlier was first in the row they had indicated. Above it or below in the row to which they now point, is the card which they originally thought of.
